Discharge from a Fire Hose The discharge from a fire hose depends on the diameter of the nozzle. Nozzle diameters are normally in multiples of
a. A nozzle of what diameter has the same discharge capacity as three combined nozzles of diameters
b. We have two 1-inch nozzles and wish to use third so that the combined discharge capacity of the three nozzles is the same as the discharge capacity of a
c. If we wish to use n hoses, each with nozzle size d, in order to have the combined discharge capacity of a single hose with nozzle size D, then we must use
